Faculty of Applied health BMS 101 gu.edu.eg By the end of this session, you will be able to: 1. Define joints & list its types 2. State muscles & mention its types 3. Classify types of skeletal muscle fibers JOINTS Meeting of 2 bones or more Fibrous joints 3 types of joints Cartilaginous joints Synovial joints Fibrous joints Fixed joints 3 Types Sutures Sutures In skull Fibrous joints In teeth Fibrous joints Cartilaginous joints 2 types Primary cartilaginous joint Secondary cartilaginous joint Primary cartilaginous joint Ossifies in adulthood Temporary joint Immobile joint Site Secondary cartilaginous joint Permanent joint Slightly mobile joint Site Intervertebral discs Symphysis pubis synovial joints Freely mobile joints Strong fibrous capsule surrounds joint Articular Cartilage Types of Synovial Joints According to axis of movement Uni-axial joints Bi-axial Multi -axial Non-axial joints Plane Movements occur Uni-axial joints around a single axis 2 Types One Long axis Pivot joint One Transverse axis Hinge joint Uni-axial joints Bi-axial joints According to shape of Articular surface Condylar joint Ellipsoid joint Saddle joint Condylar joint Ellipsoid joint Saddle joint Multi-axial joints The most freely mobile joints Around 3 axes And socket joint And hip joint Shoulder joint Plane joints muscles Muscle tissue is characterized by the property of contraction Types of muscle 1--Skeletal 2- Smooth 3- Cardiac Dr.Code: Mogeda Mahdy SOM1-1 Skeletal muscles 1- Attachment of skeletal muscles Origin: usually the most fixed attachment (proximal attachment). Insertion: usually the most mobile attachment (distal attachment). Dr.Code: Mogeda Mahdy SOM1-1 Skeletal muscles 1- Types of attachment Attachment to bone (common type) Attachment to fibrous raphe Attachment to skin Attachment to intermediate tendon Attachment to cartilage Dr. Mogeda Mahdy Code: SOM1-1 Form of Skeletal Muscles The muscle form depends on the arrangement of the muscle fibers in relation to the line of pull (line extending between the origin & insertion). Muscles with parallel fibers Dr.Code: Mogeda Mahdy SOM1-1 Form of skeletal muscle Muscles with oblique fibers Dr.Code: Mogeda Mahdy SOM1-1 Test yourself Mention type of the following joint???????????? Test yourself Mention Name & type of the following joint???????????? Thank You gu.edu.eg
